What consequence may occur if you cross a runway without air traffic control approval?

Crossing a runway without air traffic control approval can lead to severe consequences due to the critical safety protocols established in airfield operations. When a vehicle crosses a runway without the necessary clearance, it poses a significant risk not only to the vehicle's operator but also to aircraft in the vicinity. Air traffic control is responsible for ensuring the safe movement of all aircraft and vehicles on the airfield, and unauthorized runway incursions can lead to dangerous situations, including potential accidents.

In this context, immediate apprehension and suspension of driving privileges serves as a deterrent to such dangerous behavior. This consequence emphasizes the seriousness with which air traffic safety is regarded and helps to maintain the integrity of airfield operations. Ensuring that all personnel adhere to the established communication and approval protocols is paramount for maintaining safety across the airfield. Therefore, the potential for immediate apprehension and the suspension of driving privileges highlights the importance of compliance with air traffic control instructions, reflecting the gravity of the situation if protocols are ignored.
